2012年4月23日 · In reading the AISC manual, I am given to understand that slip critical bolted joints have faying (fayed) surfaces and that special care must be taken to keep the surfaces rough, with mu=0.5 or so. I have read that galvanization tends to …

2003年1月21日 · "Faying surfaces in slip-critical joints must meet the requirements in RCSC Specification Sections 3.2 and 3.2.2. RCSC defines a faying surface as “the plane of contact between two plies of a joint.” NOTE that the surfaces under the bolt head, washer and/or nut are not faying surfaces."

2010年6月22日 · When applying the BMS595 sealant to the electrical faying surface, do you also cover the electrical bond area. My interpetation of Boeing Spec BAC5117-6 Cat 2 is that you apply the sealant to the entire faying surface of one part. I'm dealing with an aluminum assy and there is a bracket to be...

2010年10月6日 · DTI "direct tension indicator", is a load indicator to verify that the bolt has adequate pretension. Slip critical is a combination of faying surface condition and bolt pretension. The slip critical shear resistance of the bolt is the same …

2014年12月19日 · As a result the modification, the beam is short and the faying surfaces of one of end-plate connections have 7/16" gap in between them. The contractor has not used any shims. Instead, they've tightened the bolts enough to deform the end-plates (with 7/16" gap still visible in the middle of plates).

2020年9月21日 · RE: Eccentrically loaded bolt normal to faying surface JLNJ (Structural) 21 Sep 20 16:10 It looks like a connection check whereby the bolted connection angle is trying to peel or pry off the face of a girder.

2012年3月16日 · My main concern is the faying surface between the galvanized and painted gusset plates and the painted diagonals. The gusset plates are to be galvanized and painted with a 2 coat paint system. The diagonal are to be blast cleaned and 3 coated painted. I have attached the connection detail for reference.

2005年5月20日 · Parts that fit poorly together, or are not clamped tightly together during assembly-fit-up, develop gaps at the mating-surfaces [faying surfaces]. Installing fasteners thru this stack-up [joint] results in exposed fastener shanks in …

2016年5月9日 · Hi all, I am looking for detailed design examples for connections with Eccentric loading, particularly Bolts with "Eccentricity Normal to the Plane of the Faying Surface", the "Elastic Method" and "Instantaneous Center of Rotation Method" as covered by AISC Steel Construction Manual Part 7. I...

2024年10月31日 · A project with completed erection, with many connections designed as Class A slip critical. The project is galvanized, so the coating is not Class A certified and the coatings are not blocked. What can be done if the erector failed to wire brush the faying surfaces? The required slip coefficient is 0.33, for Class A.
